Embodiment Construction

[0027]The basic idea of the present invention is to provide an injection device with a control valve for controlling the outlet flow rate of the injectable product depending on the pressure applied to the injectable product.

[0028]As is well known, at a given application pressure for the injectable product, the outlet flow rate (and therefore the outlet pressure) in an injection device depends on the surface of the outlet opening. At an equal application pressure, the flow rate will be less the smaller the surface of the opening. However, since the application pressure in the administration of injectable products is not usually constant, it is necessary to act on the outlet surface if the outlet pressure or flow rate is to be controlled. As the application pressure increases, the surface of the outlet opening S must be reduced so that the outlet flow rate is not greater than what is considered safe. If there were a small fixed surface S implying a small flow rate even under high appl...

Abstract

A device is for the administration of injectable products with controlled flow rate, with a container (23) in the form of both a syringe and an ampoule preloaded with the injectable product, an injection port (25) and a control valve (21) for controlling the outlet rate and pressure arranged between the injectable products and the injection port (25). A device for reducing the outlet flow rate depends on the pressure increase applied during the administration of the injectable product, the administration being moderated by closing the valve (21) when the pressure exceeds a predetermined limit. A device prevents the backflow of fluids during the administration of the injectable product. The valve (21) can be positioned both in the container (23) and at an injection end (27) including the injection port (25) which is coupled to the container (23).

Description

FIELD OF THE INVENTION[0001]The present invention relates to a device for the administration or dosing of injectable products, and more particularly to a device which allows controlling the injected flow rate.BACKGROUND OF THE INVENTION[0002]Current injection devices are generally syringe-type devices, i.e., with a plunger which is moved inside a cylinder and expels the content through one end, where the needle for injecting the liquid into the patient can be connected, or it can be connected to systems previously implanted in the patient, such as catheters.[0003]The injection flow rate is controlled by the speed of movement of the plunger, and such speed is controlled by trained and experienced healthcare personnel. Excessive flow rate can cause adverse effects in the patient such as broken veins, extravasations, etc. The same occurs with an excessive outlet pressure.[0004]With syringe-type injection devices, injectable products must be administered by healthcare professionals exce...
